Hi,
one of the new features in the 2.6.0 release is the ability to handle styles
in more than one language.
I've seen it work with CSS on the web UI, but I've just tried with REST and
I cannot seem to make it work, from what I can see it looks lilke a bug.
Here is what I've done. First, create the style xml, telling GeoServer I'm
going
to upload a css:
> curl -v -u admin:geoserver -XPOST -H "Content-type: text/xml" -d
"<style><name>test_css</name><filename>test_css.css</filename><format>css</format></style>"
http://localhost:8080/geoserver/rest/styles
* Hostname was NOT found in DNS cache
* Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 8080 (#0)
* Server auth using Basic with user 'admin'
> POST /geoserver/rest/styles HTTP/1.1
> Authorization: Basic YWRtaW46Z2Vvc2VydmVy
> User-Agent: curl/7.35.0
> Host: localhost:8080
> Accept: */*
> Content-type: text/xml
> Content-Length: 89
>
* upload completely sent off: 89 out of 89 bytes
< HTTP/1.1 *201 Created*
< Date: Thu, 11 Dec 2014 18:07:58 GMT
< Location: http://localhost:8080/geoserver/rest/styles/test_css
* Server Noelios-Restlet-Engine/1.0..8 is not blacklisted
< Server: Noelios-Restlet-Engine/1.0..8
< Transfer-Encoding: chunked
And then I'm going to upload the css file itself:
> curl -v -u admin:geoserver -XPUT -H "Content-type:
application/vnd.geoserver.geocss+css" -d @test_css.css
http://localhost:8080/geoserver/rest/styles/test_css
The upload works at least up to a certain point, but then fails with the
following stack trace:

Now, as far as I can tell, the issue is that the CSS got parsed into a
Style object by the
handler, and then the StyleResource is trying to save that Style object
(instead of the
original CSS), as it enters in the first branch of the following if:
ResourcePool resourcePool = catalog.getResourcePool();
if (object instanceof Style) {
resourcePool.writeStyle(s, (Style) object, true);
}
else {
resourcePool.writeStyle(s, (InputStream)object);
}
The conversion from Style (SLD) back to CSS is of course not supported,
and... boom.
I guess that generally speaking, the parsing and then rewriting of the
style should
be enabled only for SLD, and only for backwards compatibilty sake (in order
to
reformat the SLD, which some clients rely upon)?
Feedback welcomed
Cheers
Andrea
